IMPROVEMENT l N RELlSHlNG-MACHINES.

Specification forming part of Letters Patent No. 153,980, dated August11, 1874; application filed May 9, 1874.

-To all whom it may concern:

' ple and efficient machine to cut the tenons of sash, blind, and doorrails, and other frames, andat the same time out out the recess betweenthe ogeeshoulders of the tenon, where the cutter cannot work withoutdestroying the shoulders, to reduce width of the tenons to fit themortises.

Figure 1 is a perspective view of our improved machine. Fig. 2 is a sideelevation. Fig. 3 is a sectional elevation taken on the line a: 00 ofFig. 4.. Fig. 4 is a plan view. Fig. 5 is a horizontal section of ajoint of a sash or blind frame, showing the narrowed tenon and therecess; and Fig. 6 is a side elevation of Fig. 5.

Similar letters of reference indicate corresponding parts.

A represents a rotary cutter mounted on a horizontal shaft, J, on aframe or bench, K,

and driven by a belt, L, from a driving-pulley, M. B is the work-holdingtable for holding the rails to be relished. It is arranged on ways N, ona vertically adjustable. table, 0,

to slide toward and from the rotary cutter; and O is a boring-toolarranged alongside of the end of the cutter at right angles to its axis,but in the same horizontal plane. It is driven by a belt, P, from apulley, Q, on the driving-shaft. This boring-tool is for cutting out therecess R between the ogee projecting shoulders D, where the cuttercannot work, while the cutter dresses oli' the rest of the tenon betweenthe boring-tool and the end in the process of reducing it to the widthrequired for fitting the mortise S.

The table 0 is to be adjusted up and down to adapt it for holding railsof different thicknesses at the proper height relatively to theboring-tool and cutter to be presented to them, so that the boring-to0lwill work to the center of the tenon. I

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- The cutting-head A, in combination withboring-tool G, placed at right angles to it, and the vertically andhorizontally adjustable table 0, substantially as and for the purposespecified. v; t
